Best Agencies for ChatGPT SEO Optimization in 2026

Your CEO asked why your brand isn't showing up when a prospect asks ChatGPT to recommend a tool in your category. You don't have a clean answer. That's the moment most B2B SaaS marketing leaders realize their SEO strategy wasn't built for AI search.

The best agencies for ChatGPT SEO optimization in 2026 don't just chase Google rankings. They get your brand cited in ChatGPT, Perplexity, Google AI Mode, and Gemini by combining content structure, Reddit presence, third-party listings, entity clarity, and traditional SEO into one program. This list covers seven agencies that do this work, with notes on who each one fits and who it doesn't.

How We Evaluated These Agencies

We ranked the chosen agencies against three criteria:

• Genuine AEO methodology: A documented process for LLM citation, whether it’s via bespoke content strategy, multi-surface search optimization, or other tactics.
• Verified results: Named case studies or third-party reviews with demonstrated results.
• Pipeline and revenue focus: Results measured in demos, trials, or MRR, so you can see the impact on revenue.

7 Best Agencies for ChatGPT SEO Optimization Compared (2026)

If you're a SaaS team serious about getting your brand cited in ChatGPT, Perplexity, and Google AI Mode, and tying that visibility to demos and revenue, Scalerrs offers you a full AEO stack that includes Reddit and third-party listicle placements alongside traditional SEO.

1. Scalerrs: Best for Mid-Market & Enterprise SaaS Teams That Need ChatGPT SEO and a Multi-Surface AEO Strategy

If your buyers are researching tools inside ChatGPT and your brand isn't coming up, it’s usually because your brand isn't present enough across the sources AI models trust: Reddit, authoritative listicles, Wikipedia, YouTube, and your own structured content. Scalerrs is built specifically to fix that.

Scalerrs is a SaaS-only SEO, AEO, and Reddit marketing agency. Our playbooks, the content frameworks, and the measurement approach are specifically built for long sales cycles, PLG dynamics, and revenue attribution, not traffic charts. 

In under two years, we’ve reached roughly $2M ARR with a team of around 20, servicing 45+ SaaS clients at sub-7-8% churn. 85% of our clients have steadily hit their KPIs.

Scalerrs Key Services

Full AEO stack across every surface where AI models look

Scalerrs runs AEO as a multi-surface program, not just on-page content restructuring. The work spans Reddit marketing, Wikipedia page creation, and YouTube SEO, in addition to traditional SEO because ChatGPT and Perplexity pull answers from all of those sources. 

We also get you relevant placements in third-party listicles that make up about 85% of brand visibility in AI search. 

Plus, our content creation service aims at producing articles optimized for earning AI/LLM visibility.

Reddit marketing that actually works

Most agencies won't touch Reddit, or they post promotional content that gets removed inside 48 hours. Scalerrs enters subreddit conversations where your buyers are already active, adds genuine value first, and only mentions your brand/product when it genuinely fits the thread. Our Reddit marketing approach is white-hat and 100% community-native, rather than broadcast advertising.

And why does this matter for ChatGPT SEO specifically? 

Getting your brand mentioned authentically in active Reddit threads builds the citation weight that makes AI models more likely to name your product.

Partnership model with direct Slack access

Scalerrs operates on a partnership model, not a vendor model. Every client gets direct Slack access to the team, a 30-minute response-time guarantee, weekly updates, monthly reports, and wins surfaced as they happen rather than saved for the quarterly review. We also offer every client access to our custom client portal so they can track the status of every single deliverable in real time—from brief to publication.

Pricing

We offer flexible monthly pricing with no long-term lock-in. Book a demo to get a custom quote for your AEO program.

Where Scalerrs Shines

• SaaS-only focus: Every case study, every framework, and every team member's experience maps directly to the same buyer journey your prospects move through.
• AEO that spans the full web: We treat ChatGPT SEO as a brand presence problem, going beyond on-site optimizations. Reddit, third-party listicles, and YouTube all feed the AI citation graph that makes your brand show up, and our strategy covers them all. 
• Results defensible inside your org: Scalerrs surfaces wins mid-campaign, keeps weekly + monthly reporting tight enough to paste into leadership updates, and is explicit about connecting organic and AI search activity to pipeline.

Where Scalerrs Falls Short

• Not for pre-PMF or early-stage startups: If you haven't found product-market fit or you're running SEO budget as a make-or-break spend, Scalerrs won't be the right fit. The agency is built for companies that are past the earliest stage and ready to invest in compounding organic growth.
• Not for non-SaaS businesses: If your model isn't SaaS, the vertical expertise that makes Scalerrs effective won't translate.

Customer Reviews

Jim Hartung, Head of Growth at Morgen:

"We got to 29,000 clicks per month. That's a 3x increase in really just four or five months. Signups are up 125% year over year. It's an investment that pays off across the funnel."

Thiago Muffo, Head of Growth at Pabau:

"We're the highest-cited domain and often rank #1 for comparison queries. We also generated over 4,000 referral visits from AI search."

Who Scalerrs Is Best For

• SaaS marketing leaders (CMO, VP Marketing, Head of Growth): You own an organic growth target and need an agency that ties ChatGPT SEO to pipeline, not traffic. You want to stop explaining SEO to leadership and start handing them numbers.
• SaaS SEO and growth practitioners: You understand the strategy but need execution support (content, links, Reddit, AEO) from a team that already knows the SaaS buyer journey.

2. iPullRank: Best for Enterprise Brands That Need Technical AI Search Engineering

iPullRank is one of the most technically rigorous AI search agencies in the market. Founded by Mike King, the agency has built a methodology called Relevance Engineering that goes deeper into information retrieval theory, embeddings, and language modeling than almost any competitor.

Its client list includes American Express, SAP, HSBC, Nordstrom, Grainger, and MLB. The agency reports $5B+ in organic search results across its client portfolio. 

Key Services

• Relevance Engineering: iPullRank's proprietary framework treats SEO and AI search primarily as a technical discipline. Content is optimized for retrieval by language models using semantic content structures, passage scoring, and retrieval modeling: the same techniques LLMs use internally when deciding what to cite.
• GEO and AI Search Strategy Programs: As buyer discovery moves to AI surfaces, iPullRank runs integrated programs covering content ecosystems across the full web. The approach is built on understanding how AI bots crawl, index, and weight signals.
• Proprietary research and thought leadership: Mike King and the iPullRank team publish detailed technical research on AI search that practitioners and competitors cite. If you want to work with the people running the most technically sophisticated experiments in the field, this is the agency.

Pricing

iPullRank does not publish pricing publicly.

Where iPullRank Shines

• Deep technical AI search strategy: If your site has a complex technical architecture and your problem is that LLMs are retrieving and representing your brand inaccurately, iPullRank's Relevance Engineering approach addresses that.
• Enterprise credibility: For Fortune 500 procurement teams, the brand names in iPullRank's client roster and Mike King's public profile carry weight.

Where iPullRank Falls Short

• Price floor excludes most growth-stage SaaS: Third-party sites estimate a $50,000+ project minimum and a $12,000+/month entry point which puts iPullRank out of reach for most Series A and B companies.
• Heavy on strategy, lighter on end-to-end content production: Companies that need a full content engine alongside AI search strategy may need a second agency to handle production volume.

Customer Reviews

iPullRank doesn’t have publicly available reviews on Clutch and G2, so we’ve shared a testimonial from their website.

Tony Carpentiere, Sr. Manager of Digital Strategy and Experiences at American Express OPEN:

‍

“Ultimately, I hired Mike’s team because of his proven expertise and his results-driven approach. His ability to work well with internal and external partners and integrate his recommendations into existing marketing efforts was very valuable to the team.”

Who iPullRank Is Best For

• Enterprise and Fortune 500 brands: Companies with complex technical architectures, substantial budgets, and dedicated internal marketing teams that can implement strategic recommendations.
• Financial services, enterprise tech, and media verticals: iPullRank's client work is concentrated in these categories.

3. Quoleady: Best for SaaS Teams That Want BOFU Content and LLM Optimization Built Together

Quoleady is a SaaS-focused content marketing and SEO agency that has extended its service stack to include LLM Optimization (LLMO). The agency works with B2B SaaS companies to grow organic presence across both Google and AI platforms like ChatGPT, Gemini, and Perplexity.

Founded in 2020 and headquartered in Estonia, Quoleady operates with a team of around 35 and has worked with clients including Monday.com, Airfocus, and Expandi.io. The agency's work centers on bottom-of-funnel, high-intent content: the 20% of the content catalog that drives 80% of the conversions.

Key Services

• BOFU-first content strategy: Quoleady prioritizes high-intent, decision-stage content before scaling to top-of-funnel. That means your content budget goes toward pages where prospects are actively evaluating tools, not awareness posts that convert at low rates.
• LLMO alongside traditional SEO: Content is produced and structured with visibility in ChatGPT, Gemini, and Perplexity as an explicit goal. 

Pricing

Where Quoleady Shines

• Content quality for technical SaaS audiences: Clients consistently highlight the agency's ability to translate complex SaaS product topics into content that ranks and converts. 
• LLMO integrated at the writing stage: Rather than retrofitting AI optimization onto finished content, Quoleady builds LLMO considerations into the content production workflow from the start.

Where Quoleady Falls Short

• Primarily a content agency: If you need Reddit marketing, Wikipedia, or a broader off-page citation-building program to complement content, Quoleady's scope is narrower than full-service AEO agencies.
• Fewer public case studies on AI-referred pipeline: The strongest verified results cover traffic and rankings. Teams evaluating purely on LLM citation metrics will find less published proof.

Customer Reviews

Verified Clutch review by Product Marketing Manager, B2B E-Commerce Software Company:

“The team was highly responsive whenever I raised a concern, addressing everything quickly and professionally. The one area for growth would be more proactive communication: occasionally it felt like the process was on autopilot rather than fully adaptive partnership.”

Who Quoleady is best for

• Mid-market SaaS teams: Series A and B companies that need a consistent BOFU content engine and want LLM visibility baked in from day one.
• SaaS SEO managers with in-house strategy, needing execution: Teams that have a keyword strategy but need a partner to produce and optimize content at volume.

4. Grow and Convert: Best for SaaS Companies That Need Pain Point SEO Integrated With AI Visibility

Grow and Convert is known for Pain Point SEO: a methodology that targets keywords where buyers are expressing a specific problem rather than a generic information need. The agency has publicly argued for years that top-of-funnel content underperforms on conversion, and that BOFU content is where organic ROI actually lives. In 2026 that thesis extends directly into AI search.

Key Services

• Pain Point SEO methodology: Content is built around the specific problems your buyers are articulating in communities, forums, and search, instead of generic informational queries. 
• AI search research and application: Grow and Convert publishes substantive research on how AI search handles different types of queries. That thinking is applied to client content programs.
• Conversion-focused content writing: The agency prioritizes converting blog readers into paying customers, not just driving traffic. Case studies focus on paid customer acquisition.

Pricing

Where Grow and Convert Shines

• BOFU alignment with how AI search actually works: Pain Point SEO content is exactly what LLMs prefer to cite when recommending vendors. The methodology and the AI search moment are well-matched.
• Transparent methodology: The agency explains its approach publicly in enough detail that you can evaluate whether it fits your content strategy before getting on a call.
• Proprietary tool access: All Grow and Convert SEO/GEO clients get the proprietary AI visibility tracking tool (Traqer.ai) included free during their engagement; the agency sets it up, manages it, and reports from it.

Where Grow and Convert Falls Short

• Primarily a content strategy agency: If you need Reddit, Wikipedia, entity-building, or a broader multi-surface AEO program, it’s not the best fit. Grow and Convert's scope centers on content. Off-page citation building requires a separate partner.
• Writer quality can vary: One Clutch reviewer praised the agency's methodology and a specific top-performing writer, but noted quality dropped when that writer transitioned off their account.

Customer Reviews

Verified Clutch review by National Manager, Healthcare Center:

“Their knowledge and execution of pain-point SEO and the quality of the reporting and writing (with the first writer we had -- when she left the project, the other writer wasn't a good fit so we ended our relationship). They definitely know their stuff and have a great formula going.”

Who Grow and Convert Is Best For

• Mid-market SaaS with measurable conversion events: Companies that track blog-to-trial or blog-to-demo conversions and want a methodology that optimizes explicitly for those outcomes.
• B2B SaaS teams with $10K+ monthly SEO budget: The retainer minimum assumes you're past the point of treating SEO as a nice-to-have.

5. Seer Interactive: Best for Enterprise Brands Running Rigorous GEO Testing

Seer Interactive is a Philadelphia-based digital marketing agency founded in 2002. With a 92% client retention rate, Seer is one of the most established full-service search agencies in the US. It publishes its GEO experiments, data, and findings publicly, including tests that don't work.

Key Services

• Productized GEO service: Seer runs a formalized GEO program, not a bolt-on AI search package. Its 2026 research across 231,347 LLM responses provides the empirical basis for the approach.
• Rapid testing and transparent sharing: Seer is one of very few agencies that publishes actual test data from client campaigns, including what doesn't work. For enterprise marketing teams under scrutiny, that transparency is credibility.
• Full-service integration: SEO, paid media, analytics, creative, CRO, and GEO operate under one roof. For enterprise teams that want one agency managing multiple channels, Seer offers that coverage.

Pricing

Where Seer Interactive Shines

• Genuine GEO research depth: If you want an agency that has run the experiments and published the data, not just adopted the terminology, Seer is one of a small number that qualifies.
• Multi-channel integration: For enterprise brands that don't want to manage separate SEO, paid, and AI search agencies, Seer's full-service model is a good option.

Where Seer Interactive Falls Short

• Pipeline attribution less prominent: Most Seer case studies report on traffic, AI visibility, and conversion metrics rather than pipeline and revenue outcomes. If your leadership needs to see revenue attribution, push for specifics during the sales process.

Customer Reviews

Verified Clutch review by Associate Department Director, Drexel University

“I appreciate Seer Interactive's professionalism, attention to detail, and industry knowledge of the current landscape and the future of search.”

Who Seer Interactive Is Best For

• Enterprise technology and multi-channel brands: Large organizations that need SEO, paid, and GEO under one agency relationship and have budgets to match.

6. Optimist: Best for B2B SaaS and Tech Companies Measuring SEO and AEO Against Pipeline

Optimist is a B2B SaaS and technology-focused SEO and AEO agency based in Iowa. The agency's CORE Framework (Complete Organic Revenue Engine) maps both SEO and AEO objectives across the full buyer journey in one integrated system.

Pricing starts at $3,000/month for advisory retainers and $4,000/month for full-service engagements, with one-time strategy engagements from $7,500.

Potential limitation: Optimist is a small, senior-practitioner team, not a high-volume content shop. Companies that need large-scale content production or Fortune 500 enterprise account management may outgrow the model.

7. Omnius: Best for European SaaS, Fintech, and AI Companies

Omnius is a London-based B2B SEO and GEO agency founded in 2021, working exclusively with SaaS, Fintech, and AI/LLM companies. The agency limits intake to roughly eight clients per year, with all work done in-house by a team that completes a 12-week internal Academy.

Omnius has built a proprietary tracking tool called AtomicAGI for monitoring brand visibility across ChatGPT, Perplexity, Claude, and Gemini. The boutique model and hyper-narrow vertical focus (SaaS, Fintech, AI only) mean senior involvement is the norm rather than the exception. Pricing is custom and not published publicly. Notable clients include TextCortex, Meniga, WorldFirst, and Airbnb.

Limited annual intake means availability is restricted, and the lack of public pricing or Clutch reviews makes pre-sales evaluation harder than with agencies that publish both.

How to Choose the Right Agency for ChatGPT SEO Optimization

We recommend asking your agency the following questions before you sign with them:

Does the agency treat AI search as an on-site or whole-web problem?

On-page AEO optimization (answer blocks, schema, structured content) matters. But ChatGPT and Perplexity pull brand signals from Reddit, listicles, Wikipedia, YouTube, and the broader web, too. Ask every agency how they build citation presence off-site.

Can the agency show you AI-referred traffic or pipeline, not just citation counts?

Citation counts are an input metric. What you should care about is whether AI-referred traffic converts into demos, trials, or closed deals. Agencies running genuine AEO programs can show AI referral data in GA4 and connect it to conversion events. If the proof only runs to "we improved your brand's share of voice in ChatGPT," push harder.

Does the agency understand buyer journeys for your industry specifically?

Buyer journeys differ by industry, and your agency needs to understand yours. 

SaaS, for example, has longer sales cycles, lower tolerance for TOFU content that never converts, and PLG dynamics that change how you attribute organic. An agency that serves SaaS, e-commerce, and local businesses simultaneously will likely apply a generalist playbook to a specialized problem. 

What does the partnership model actually look like day-to-day?

A 92% retention rate sounds good on a website. What matters is whether you have direct access to senior practitioners, how fast the team responds when something is wrong, and whether wins get surfaced proactively or buried in a monthly PDF. Ask for a sample report and a description of the communication cadence before you sign.

FAQs‍

1. What does a ChatGPT SEO optimization agency actually do?

It optimizes your brand's presence across the sources large language models draw on when answering buyer queries. That includes on-site content structure (answer blocks, schema, FAQ formatting), off-site citation building (Reddit, Wikipedia, third-party listicles, review platforms), entity clarity, and tracking AI-referred traffic and conversions in GA4.

2. Is ChatGPT SEO the same as AEO or GEO?

Sometimes. AEO (Answer Engine Optimization) and GEO (Generative Engine Optimization) are the two most common labels for optimizing content to be cited in AI-generated answers. ChatGPT SEO is a buyer-friendly term for the same work. In practice, agencies use all three interchangeably, so focus on the specific deliverables: citation tracking, off-page brand presence, and pipeline attribution, rather than the label.

3. How long does it take to see results from ChatGPT SEO?

It depends on your starting brand authority and how much of your content already ranks on Google. Agencies with genuine AEO programs typically see measurable AI citation improvement within 60-90 days. Pipeline impact from AI-referred traffic usually follows in the three-to-six-month window, consistent with organic SEO timelines.
